Description

technical field

[0001] The invention belongs to the technical field of hybrid electric vehicle control, and relates to a fast start-stop system of a hybrid electric vehicle engine and a control method thereof. Background technique

[0002] The global oil crisis and environmental pollution coupled with the current intensified financial crisis have made energy saving and environmental protection two major themes in the development of the automobile industry. Today, when the number of cars in the world is close to 1 billion, it is the general trend to develop more energy-efficient cars. Due to the huge number of cars in the world, under the condition that the urban population continues to grow and the number of cars is increasing, vehicle exhaust emissions make the urban air quality continue to decline, and has become the number one "killer" of air quality. Therefore, the development of more environmentally friendly cars is also An imperative for the automotive industry. New ...
